PROCESS FOR THE PREPARATION OF SILICONE POLYMER/SOLID PREMIXES HAVING A HIGH FILLER CONTENT

摘要

A silicone polymer/solid premix may be prepared by incorporating into (A) a mixt ure comprising (a) 50 to 100 parts by weight of at least one polyorganosiloxane cont aining up to 5 mol % of crosslinkable groups, and (b) 5 to 200 parts by weight of at least on e readily volatile organosilicon compound containing no hydrolyzable groups, 100 to 500 pa rts by weight of (B) a solid, thereby forming a composition; removing (b) said organosi licon compound (b) from said composition; and then subjecting said composition to mech anical stress.
